Analysis of World Happiness Index (2015 - 2020)

Overview:

Finland was ranked the happiest country in the world, according to the World Happiness Report from 2021. The Nordic country scored 7.89 on a scale from 0 to 10. Two other Nordic countries, Iceland and Denmark, followed with a second and third place, respectively. The World Happiness Report is a landmark survey of the state of global happiness that ranks countries by how happy their citizens perceive themselves to be. The measurement of subjective well-being relies on three main indicators: life evaluations, positive emotions, and negative emotions.
